DESCRIPTION:Gravity coupled to a massless scalar field with full cylindric
 al symmetry can be exactly quantized by an extension of the techniques use
 d for Einstein-Rosen waves. We will obtain the quantum Hamiltonian operato
 r and the unitary evolution operator for this gravitational system. Afterw
 ards\, we will use it as a testbed to discuss a number of issues in quantu
 m general relativity. Specifically\, we will study two-point functions and
  radial wave functions for one-particle states. Some interesting effects a
 ppear such as the emergence of null geodesics\, the large probability ampl
 itude to find the particles near the axis of symmetry... To conclude\, we 
 will discuss also the possibility of constructing coherent states for this
  model.\n\nhttps://indico.ific.uv.es/event/1628/
